Google search while better does not block ads, WCM default search does not provide hot links
While the Google search engine is much better, it doesn't rank the latest changes at the top so older documents found and no longer active are brought forward in the search (archived and not active policy documents) and the Find It can not search on multiple words. WCM search is very limited in that the links are not hot and searches for policy documents are not recognizable. Searching is a bear!

I agree, Google Search is nice, but having to manage the search index through a separate system is burdensome and not always effective. I would recommend looking into Google Custom Search for non-profits though, as we were able to have ads removed by registering as a school.
